1.1 About Your WiMAX Modem
The WiMAX Modem has a built-in switch and one phone port. It allows you to
access the Internet by connecting to a WiMAX wireless network.
You can use a traditional analog telephone to make Internet calls using the WiMAX
Modem’s Voice over IP (VoIP) communication capabilities.
You can configure firewall and content filtering as well as a host of other features.
The web browser-based Graphical User Interface (GUI), also known as the web
configurator, provides easy management.
See Chapter 18 on page 177 for a complete list of features for your model.
1.1.1 WiMAX Internet Access
Connect your computer or network to the WiMAX Modem for WiMAX Internet
access. See the Quick Start Guide for instructions on hardware connection.
In a wireless metropolitan area network (MAN), the WiMAX Modem connects to a
WiMAX base station (BS) for Internet access.
The following diagram shows a notebook computer equipped with the WiMAX
Modem connecting to the Internet through a WiMAX base station (marked BS).
Figure 1 Mobile Station and Base Station
When the firewall is on, all incoming traffic from the Internet to your network is
blocked unless it is initiated from your network.
User’s Guide

Chapter 1 Getting Started
Use content filtering to block access to web sites with URLs containing keywords
that you specify. You can define time periods and days during which content
filtering is enabled and include or exclude particular computers on your network
from content filtering. For example, you could block access to certain web sites for
the kids.
1.1.2 Make Calls via Internet Telephony Service Provider
In a home or small office environment, you can use the WiMAX Modem to make
and receive the following types of VoIP telephone calls:
• Peer-to-Peer calls - Use the WiMAX Modem to make a call directly to the
recipient’s IP address without using a SIP proxy server.
Figure 2 WiMAX Modem’s VoIP Features - Peer-to-Peer Calls
• Calls via a VoIP service provider - The WiMAX Modem sends your call to a VoIP
service provider’s SIP server which forwards your calls to either VoIP or PSTN
phones.

1.3 Good Habits for Managing the WiMAX
Modem
Do the following things regularly to make the WiMAX Modem more secure and to
manage the WiMAX Modem more effectively.
• Change the password. Use a password that’s not easy to guess and that consists
of different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it).
Restoring an earlier working configuration may be useful if the WiMAX Modem
becomes unstable or even crashes. If you forget your password, you will have to
reset the WiMAX Modem to its factory default settings. If you backed up an
earlier configuration file, you would not have to totally re-configure the WiMAX
Modem. You could simply restore your last configuration.

The Setup Screens
3.1 Overview
Use these screens to configure or view LAN, DHCP Client and WAN settings.
3.1.1 What You Can Do in This Chapter
• The Set IP Address (LAN 設定 ) screen (Section 3.2 on page 32) lets you
configure the WiMAX Modem’s IP address and subnet mask.
• The DHCP Client (DHCP 用戶端 ) screen (Section 3.3 on page 33) lets you view
all DHCP client information.
• The Time Setting (時間設定) screen (Section 3.4 on page 35) lets you configure
your WiMAX Modem’s time and date keeping settings.
3.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
LAN
A Local Area Network, or a shared communication system to which many
computers are attached. A LAN, as its name implies, is limited to a local area such
as a home or office environment. LANs have different topologies, the most
common being the linear bus and the star configuration.
IP Address
IP addresses identify individual devices on a network. Every networking device
(including computers, servers, routers, printers, etc.) needs an IP address to
communicate across the network. These networking devices are also known as
hosts.
Subnet Mask
The subnet mask specifies the network number portion of an IP address. Your
device will compute the subnet mask automatically based on the IP Address that
User’s Guide
31
Chapter 3 The Setup Screens
you entered. You do not need to change the computer subnet mask unless you are
instructed to do so.
DHCP
Your WiMAX Modem can act as a DHCP (Dynamic Host Configuration Protocol)
server that can assign your LAN computers an IP address, subnet mask, DNS and
other routing information when its LAN DHCP feature is turned on.
Daytime
A network protocol used by devices for debugging and time measurement. A
computer can use this protocol to set its internal clock but only if it knows in which
order the year, month, and day are returned by the server. Not all servers use the
same format.
Time
A network protocol for retrieving the current time from a server. The computer
issuing the command compares the time on its clock to the information returned
by the server, adjusts itself automatically for time zone differences, then
calculates the difference and corrects itself if there has been any temporal drift.
NTP
NTP stands for Network Time Protocol. It is employed by devices connected to the
Internet in order to obtain a precise time setting from an official time server.
These time servers are accurate to within 200 microseconds.
3.1.3 Before You Begin
• Make sure that you have made all the appropriate hardware connections to the
WiMAX Modem, as described in the Quick Start Guide.
• Make sure that you have logged in to the web configurator at least one time and
changed your password from the default, as described in the Quick Start Guide.

3.4.1 Pre-Defined NTP Time Servers List
The WiMAX Modem uses a pre-defined list of NTP time servers if you do not
specify a time server or it cannot synchronize with the time server you specified.
It can use this list regardless of the time protocol you select.
When the WiMAX Modem uses the list, it randomly selects one server and tries to
synchronize with it. If the synchronization fails, then it goes through the rest of
the list in order until either it is successful or all the pre-defined NTP time servers
have been tried.

The LAN Configuration Screens
5.1 Overview
Use the ADVANCED > LAN Configuration screens to set up the WiMAX Modem
on the LAN. You can configure its IP address and subnet mask, DHCP services, and
other subnets. You can also control how the WiMAX Modem sends routing
information using RIP.
A Local Area Network (LAN) is a shared communication system to which many
computers are attached. A LAN is usually a computer network limited to the
immediate area, such as the same building or floor of a building.
5.1.1 What You Can Do in This Chapter
• The DHCP Setup screen (Section 5.2 on page 46) lets you enable, disable, and
configure the DHCP server in the WiMAX Modem.
• The Static DHCP screen (Section 5.3 on page 47) lets you assign specific IP
addresses to specific computers on the LAN.
• The IP Alias screen (Section 5.4 on page 49) lets you add subnets on the LAN
port. You can also control what routing information is sent and received by each
subnet.
• The IP Static Route screen (Section 5.5 on page 51) lets you examine the
static routes configured in the WiMAX Modem.
• The Other Settings screen (Section 5.6 on page 53) lets you control the
routing information that is sent and received by each subnet assign specific IP
addresses to specific computers on the LAN.
5.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
IP Address
IP addresses identify individual devices on a network. Every networking device
(including computers, servers, routers, printers, etc.) needs an IP address to

45
Chapter 5 The LAN Configuration Screens
communicate across the network. These networking devices are also known as
hosts.
Subnet Masks
Subnet masks determine the maximum number of possible hosts on a network.
You can also use subnet masks to divide one network into multiple sub-networks.
DNS
DNS (Domain Name System) is for mapping a domain name to its corresponding
IP address and vice versa. The DNS server is extremely important because
without it, you must know the IP address of a networking device before you can
access it.
DHCP
A DHCP (Dynamic Host Configuration Protocol) server can assign your WiMAX
Modem an IP address, subnet mask, DNS and other routing information when it’s
turned on.

Multicast
You do not have to enable multicasting to use RIP-2M. (See RIP
Version.)
Select which version of IGMP the WiMAX Modem uses to support
multicasting on the LAN. Multicasting sends packets to some computers
on the LAN and is an alternative to unicasting (sending packets to one
computer) and broadcasting (sending packets to every computer).
•
•
•
None - The WiMAX Modem does not support multicasting.
IGMP-v1 - The WiMAX Modem supports IGMP version 1.
IGMP-v2 - The WiMAX Modem supports IGMP version 2.
Multicasting can improve overall network performance. However, it
requires extra processing and generates more network traffic. In
addition, other computers on the LAN have to support the same version
of IGMP.

5.7 Technical Reference
The following section contains additional technical information about the WiMAX
Modem features described in this chapter.
5.7.1 IP Address and Subnet Mask
Similar to the way houses on a street share a common street name, computers on
a LAN share one common network number.
Where you obtain your network number depends on your particular situation. If
the ISP or your network administrator assigns you a block of registered IP
addresses, follow their instructions in selecting the IP addresses and the subnet
mask.
If the ISP did not explicitly give you an IP network number, then most likely you
have a single user account and the ISP will assign you a dynamic IP address when
the connection is established. If this is the case, it is recommended that you select
a network number from 192.168.0.0 to 192.168.255.0 and you must enable the
Network Address Translation (NAT) feature of the WiMAX Modem. The Internet
Assigned Number Authority (IANA) reserved this block of addresses specifically for
private use; please do not use any other number unless you are told otherwise.
Let's say you select 192.168.1.0 as the network number; which covers 254
individual addresses, from 192.168.100.1 to 192.168.1.254 (zero and 255 are
reserved). In other words, the first three numbers specify the network number
while the last number identifies an individual computer on that network.
54
User’s Guide
Chapter 5 The LAN Configuration Screens
Once you have decided on the network number, pick an IP address that is easy to
remember, for instance, 192.168.100.1, for your WiMAX Modem, but make sure
that no other device on your network is using that IP address.
The subnet mask specifies the network number portion of an IP address. Your
WiMAX Modem will compute the subnet mask automatically based on the IP
address that you entered. You don't need to change the subnet mask computed by
the WiMAX Modem unless you are instructed to do otherwise.
5.7.2 DHCP Setup
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients to obtain TCP/IP configuration at start-up from a server. You can
configure the WiMAX Modem as a DHCP server or disable it. When configured as a
server, the WiMAX Modem provides the TCP/IP configuration for the clients. If
DHCP service is disabled, you must have another DHCP server on your LAN, or
else each computer must be manually configured.
The WiMAX Modem is pre-configured with a pool of IP addresses for the DHCP
clients (DHCP Pool). See the product specifications in the appendices. Do not
assign static IP addresses from the DHCP pool to your LAN computers.
These parameters should work for the majority of installations. If your ISP gives
you explicit DNS server address(es), see Section 5.3 on page 47.
5.7.3 LAN TCP/IP
The WiMAX Modem has built-in DHCP server capability that assigns IP addresses
and DNS servers to systems that support DHCP client capability.
The LAN parameters of the WiMAX Modem are preset in the factory with the
following values:
• IP address of 192.168.100.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If your ISP gives
you explicit DNS server address(es), see Section 5.3 on page 47.
5.7.4 DNS Server Address
DNS (Domain Name System) is for mapping a domain name to its corresponding
IP address and vice versa. The DNS server is extremely important because
without it, you must know the IP address of a machine before you can access it.
User’s Guide
55
Chapter 5 The LAN Configuration Screens
The DNS server addresses that you enter in the DHCP setup are passed to the
client machines along with the assigned IP address and subnet mask.
There are two ways that an ISP disseminates the DNS server addresses. The first
is for an ISP to tell a customer the DNS server addresses, usually in the form of an
information sheet, when s/he signs up. If your ISP gives you the DNS server
addresses, enter them in the DNS Server fields in DHCP Setup, otherwise, leave
them blank.
Some ISPs choose to pass the DNS servers using the DNS server extensions of
PPP IPCP (IP Control Protocol) after the connection is up. If your ISP did not give
you explicit DNS servers, chances are the DNS servers are conveyed through IPCP
negotiation. The WiMAX Modem supports the IPCP DNS server extensions through
the DNS proxy feature.
If the Primary and Secondary DNS Server fields in the LAN Setup screen are
not specified, for instance, left as 0.0.0.0, the WiMAX Modem tells the DHCP
clients that it itself is the DNS server. When a computer sends a DNS query to the
WiMAX Modem, the WiMAX Modem forwards the query to the real DNS server
learned through IPCP and relays the response back to the computer.
Please note that DNS proxy works only when the ISP uses the IPCP DNS server
extensions. It does not mean you can leave the DNS servers out of the DHCP
setup under all circumstances. If your ISP gives you explicit DNS servers, make
sure that you enter their IP addresses in the LAN Setup screen. This way, the
WiMAX Modem can pass the DNS servers to the computers and the computers can
query the DNS server directly without the WiMAX Modem’s intervention.
5.7.5 RIP Setup
RIP (Routing Information Protocol) allows a router to exchange routing
information with other routers. The RIP Direction field controls the sending and
receiving of RIP packets. When set to:
• Both - the WiMAX Modem will broadcast its routing table periodically and
incorporate the RIP information that it receives.
• In Only - the WiMAX Modem will not send any RIP packets but will accept all
RIP packets received.
• Out Only - the WiMAX Modem will send out RIP packets but will not accept any
RIP packets received.
• None - the WiMAX Modem will not send any RIP packets and will ignore any RIP
packets received.
The Version field controls the format and the broadcasting method of the RIP
packets that the WiMAX Modem sends (it recognizes both formats when
receiving). RIP-1 is universally supported; but RIP-2 carries more information.
56
User’s Guide
Chapter 5 The LAN Configuration Screens
RIP-1 is probably adequate for most networks, unless you have an unusual
network topology.
Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference
being that RIP-2B uses subnet broadcasting while RIP-2M uses multicasting.
5.7.6 Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1
sender - 1 recipient) or Broadcast (1 sender - everybody on the network).
Multicast delivers IP packets to a group of hosts on the network - not everybody
and not just 1.
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a Multicast group - it is not used to carry user data. IGMP
version 2 (RFC 2236) is an improvement over version 1 (RFC 1112) but IGMP
version 1 is still in wide use. If you would like to read more detailed information
about interoperability between IGMP version 2 and version 1, please see sections
4 and 5 of RFC 2236. The class D IP address is used to identify host groups and
can be in the range 224.0.0.0 to 239.255.255.255. The address 224.0.0.0 is not
assigned to any group and is used by IP multicast computers. The address
224.0.0.1 is used for query messages and is assigned to the permanent group of
all IP hosts (including gateways). All hosts must join the 224.0.0.1 group in order
to participate in IGMP. The address 224.0.0.2 is assigned to the multicast routers
group.
The WiMAX Modem supports both IGMP version 1 (IGMP-v1) and IGMP version 2
(IGMP-v2). At start up, the WiMAX Modem queries all directly connected
networks to gather group membership. After that, the WiMAX Modem periodically
updates this information. IP multicasting can be enabled/disabled on the WiMAX
Modem LAN and/or WAN interfaces in the web configurator (LAN; WAN). Select
None to disable IP multicasting on these interfaces.

The WIFI Configuration Screen
6.1 Overview
Wi-Fi is a wireless networking technology and it is a synonym for wireless LAN.
The blue circle marks a wireless LAN in the following figure. Wireless clients (A and
B) connect to an access point (AP) to access other devices (such as the printer) or
the Internet. Your WiMAX Modem works as an AP when you install a compatible
WLAN card.

Chapter 6 The WIFI Configuration Screen
• Use the General screen (see Section 6.2 on page 63) to turn the wireless
connection on or off, set up wireless security, configure the MAC filter, set up
Quality of Service and make other basic configuration changes.
• Use the MAC Filter screen (see Section 6.3 on page 69) to configure a MAC
(Media Access Control) address filter to restrict access to the wireless network.
You don’t necessarily need to use all these screens to set up your wireless
connection. For example, you may just want to set up a network name, a wireless
radio channel and some security in the AP screen.
6.1.2 What You Need to Know About WIFI
Wireless Basics
• Every device in the same wireless network must use the same Service Set
IDentity (SSID).
The SSID is the name of the wireless network.
• If two wireless networks overlap, they should use different channels.
Like radio stations or television channels, each wireless network uses a specific
channel, or frequency, to send and receive information.
Wireless Network Construction
Wireless networks consist of wireless clients, access points and bridges.
• A wireless client is a radio connected to a user’s computer.
• An access point is a radio with a wired connection to a network, which can
connect with numerous wireless clients and let them access the network.
• A bridge is a radio that relays communications between access points and
wireless clients, extending a network’s range.
Traditionally, a wireless network operates in one of two ways.
• An “infrastructure” type of network has one or more access points and one or
more wireless clients. The wireless clients connect to the access points.
• An “ad-hoc” type of network is one in which there is no access point. Wireless
clients connect to one another in order to exchange information.
Wired Equivalent Privacy (WEP)
WEP (Wired Equivalent Privacy) encrypts data transmitted between wired and
wireless networks to keep the transmission private. Although one of the original
wireless encryption protocols, WEP is also the weakest. Many people use it strictly
to deter unintentional usage of their wireless network by outsiders.
Authentication Type
60
User’s Guide
Chapter 6 The WIFI Configuration Screen
The IEEE 802.11b/g standard describes a simple authentication method between
the wireless stations and AP. Three authentication types are defined: Auto, Open
and Shared. The WiMAX Modem supports the WEP (Open) and WEP (Shared)
authentication types.
• Open mode is implemented for ease-of-use and when security is not an issue.
The wireless station and the AP or peer computer do not share a secret key.
Thus the wireless stations can associate with any AP or peer computer and listen
to any transmitted data that is not encrypted.
• Shared mode involves a shared secret key to authenticate the wireless station
to the AP or peer computer. This requires you to enable the wireless LAN
security and use same settings on both the wireless station and the AP or peer
computer.
Wi-Fi Protected Access (WPA)
WPA encrypts data transmitted between wired and wireless networks to keep the
transmission private. It affords vastly stronger security than its lower-tier
counterpart, WEP (Wired Equivalent Privacy). It comes in two different flavors:
WPA and WPA2. Always try to use WPA2 as it implements the full version of the
security standard while WPA does not.
WPA2
WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger
encryption, authentication and key management than WPA. It includes two data
encryption algorithms, Temporal Key Integrity Protocol (TKIP) and Advanced
Encryption Standard (AES) in the Counter mode with Cipher block chaining
Message authentication Code Protocol (CCMP). WPA2 reduces the number of key
exchange messages from six to four (CCMP 4-way handshake) and shortens the
time required to connect to a network. Other WPA2 authentication features that
are different from WPA include key caching and pre-authentication. These two
features are optional and may not be implemented in all wireless devices. See also
WPA.
Pre-Shared Key (PSK)
A pre-shared key is a password shared between the server and the client that
unlocks the algorithm used to encrypt the data traffic between them. Without the
proper password, the client and the server cannot communicate.

Security stops unauthorized devices from using the wireless network. It can also
protect the information that is sent in the wireless network.Use the strongest
security that every wireless client in the wireless network supports.

Note: WPA2 or WPA2-PSK security is recommended.
• WPA2-PSK and WPA-PSK do not employ user authentication and are known as
the personal version of WPA.
• WEP is better than no security, but it is still possible for unauthorized devices to
figure out the original information pretty quickly.
AES
Advanced Encryption Standard is method of data encryption that uses a secret
key. AES may use a 128-bit, 192-bit or 256-bit key. AES is faster than 3DES.
TKIP
Temporal Key Integrity Protocol (TKIP) is an encryption protocol that uses 128-bit
keys that are dynamically generated and distributed by the authentication server.
TKIP regularly changes and rotates the encryption keys so that the same
encryption key is never used twice.
MAC Address Filter
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC
address consists of twelve hexadecimal characters (0-9, and A to F), and it is
usually written in the following format: “0A:A0:00:BB:CC:DD”.
62
User’s Guide
Chapter 6 The WIFI Configuration Screen
The MAC address filter controls access to the wireless network. You can use the
MAC address of each wireless client to allow or deny access to the wireless
network.
Finding Out More
• See Chapter 3 on page 31 for a tutorial showing how to set up your wireless
connection in an example scenario.
• See Section 6.4 on page 70 for advanced technical information on wireless
networks.
6.1.3 Before You Start
Before you start using these screens, ask yourself the following questions. See
Section 6.1.2 on page 60 if some of the terms used here do not make sense to
you.
• What wireless standards do the other wireless devices support (IEEE 802.11g,
for example)? What is the most appropriate standard to use?
• What security options do the other wireless devices support (WPA-PSK, for
example)? What is the best one to use?
• Do the other wireless devices support WPS (Wi-Fi Protected Setup)? If so, you
can set up a well-secured network very easily.
Even if some of your devices support WPS and some do not, you can use WPS to
set up your network and then add the non-WPS devices manually, although this
is somewhat more complicated to do.
• What advanced options do you want to configure, if any? If you want to
configure advanced options such as Quality of Service, ensure that you know
precisely what you want to do. If you do not want to configure advanced
options, leave them alone.

The following table describes some wireless network terms and acronyms used in
the WiMAX Modem’s Web Configurator.
Table 23 Additional Wireless Terms
TERM
DESCRIPTION
RTS/CTS Threshold
In a wireless network which covers a large area, wireless devices
are sometimes not aware of each other’s presence. This may cause
them to send information to the AP at the same time and result in
information colliding and not getting through.
By setting this value lower than the default value, the wireless
devices must sometimes get permission to send information to the
WiMAX Modem. The lower the value, the more often the devices
must get permission.
If this value is greater than the fragmentation threshold value (see
below), then wireless devices never have to get permission to send
information to the WiMAX Modem.
Preamble
A preamble affects the timing in your wireless network. There are
two preamble modes: long and short. If a device uses a different
preamble mode than the WiMAX Modem does, it cannot
communicate with the WiMAX Modem.
Authentication
The process of verifying whether a wireless device is allowed to use
the wireless network.
Fragmentation
Threshold
A small fragmentation threshold is recommended for busy networks,
while a larger threshold provides faster performance if the network
is not very busy.
6.4.2 Wireless Security Overview
The following sections introduce different types of wireless security you can set up
in the wireless network.
6.4.2.1 SSID
Normally, the WiMAX Modem acts like a beacon and regularly broadcasts the SSID
in the area. You can hide the SSID instead, in which case the WiMAX Modem does
not broadcast the SSID. In addition, you should change the default SSID to
something that is difficult to guess.
This type of security is fairly weak, however, because there are ways for
unauthorized wireless devices to get the SSID. In addition, unauthorized wireless
devices can still see the information that is sent in the wireless network.
6.4.2.2 MAC Address Filter
Every device that can use a wireless network has a unique identification number,
called a MAC address.1 A MAC address is usually written using twelve hexadecimal
User’s Guide
71
Chapter 6 The WIFI Configuration Screen
characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC
address for each device in the wireless network, see the device’s User’s Guide or
other documentation.
You can use the MAC address filter to tell the WiMAX Modem which devices are
allowed or not allowed to use the wireless network. If a device is allowed to use
the wireless network, it still has to have the correct information (SSID, channel,
and security). If a device is not allowed to use the wireless network, it does not
matter if it has the correct information.
This type of security does not protect the information that is sent in the wireless
network. Furthermore, there are ways for unauthorized wireless devices to get the
MAC address of an authorized device. Then, they can use that MAC address to use
the wireless network.
6.4.2.3 User Authentication
Authentication is the process of verifying whether a wireless device is allowed to
use the wireless network. You can make every user log in to the wireless network
before they can use it. However, every device in the wireless network has to
support IEEE 802.1x to do this.
For wireless networks, you can store the user names and passwords for each user
in a RADIUS server. This is a server used in businesses more than in homes. If you
do not have a RADIUS server, you cannot set up user names and passwords for
your users.
Unauthorized wireless devices can still see the information that is sent in the
wireless network, even if they cannot use the wireless network. Furthermore,
there are ways for unauthorized wireless users to get a valid user name and
password. Then, they can use that user name and password to use the wireless
network.
6.4.2.4 Encryption
Wireless networks can use encryption to protect the information that is sent in the
wireless network. Encryption is like a secret code. If you do not know the secret
code, you cannot understand the message.
72
1.
Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks.

The types of encryption you can choose depend on the type of authentication.
(See Section 6.4.2.3 on page 72 for information about this.)
Table 24 Types of Encryption for Each Type of Authentication
NO AUTHENTICATION RADIUS SERVER
Weakest
No Security
Static WEP
WPA-PSK
WPA
Strongest
WPA2-PSK
WPA2
For example, if the wireless network has a RADIUS server, you can choose WPA
or WPA2. If users do not log in to the wireless network, you can choose no
encryption, Static WEP, WPA-PSK, or WPA2-PSK.
Usually, you should set up the strongest encryption that every device in the
wireless network supports. For example, suppose you have a wireless network
with the WiMAX Modem and you do not have a RADIUS server. Therefore, there is
no authentication. Suppose the wireless network has two devices. Device A only
supports WEP, and device B supports WEP and WPA. Therefore, you should set up
Static WEP in the wireless network.
Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger
encryption. The other types of encryption are better than none at all, but it is still
possible for unauthorized wireless devices to figure out the original information
pretty quickly.
When you select WPA2 or WPA2-PSK in your WiMAX Modem, you can also select
an option (WPA compatible) to support WPA as well. In this case, if some of the
devices support WPA and some support WPA2, you should set up WPA2-PSK or
WPA2 (depending on the type of wireless network login) and select the WPA
compatible option in the WiMAX Modem.
Many types of encryption use a key to protect the information in the wireless
network. The longer the key, the stronger the encryption. Every device in the
wireless network must have the same key.
6.4.3 MBSSID
Traditionally, you needed to use different APs to configure different Basic Service
Sets (BSSs). As well as the cost of buying extra APs, there was also the possibility
of channel interference. The WiMAX Modem’s MBSSID (Multiple Basic Service Set
IDentifier) function allows you to use one access point to provide several BSSs
simultaneously. You can then assign varying QoS priorities and/or security modes
to different SSIDs.
User’s Guide
73
Chapter 6 The WIFI Configuration Screen
Wireless devices can use different BSSIDs to associate with the same AP.
6.4.3.1 Notes on Multiple BSSs
• A maximum of eight BSSs are allowed on one AP simultaneously.
• You must use different keys for different BSSs. If two wireless devices have
different BSSIDs (they are in different BSSs), but have the same keys, they
may hear each other’s communications (but not communicate with each other).
• MBSSID should not replace but rather be used in conjunction with 802.1x
security.
6.4.4 Wireless Distribution System (WDS)
The WiMAX Modem can act as a wireless network bridge and establish WDS
(Wireless Distribution System) links with other APs. You need to know the MAC
addresses of the APs you want to link to. Once the security settings of peer sides
match one another, the connection between devices is made.
At the time of writing, WDS security is compatible with other ZyXEL access points
only. Refer to your other access point’s documentation for details.
The following example illustrates how WDS link works between APs. Notebook
computer A is a wireless client connecting to access point AP 1. AP 1 has no
wired Internet connection, but can establish a WDS link with access point AP 2,
which does. When AP 1 has a WDS link with AP 2, the notebook computer can
access the Internet through AP 2.

6.4.5 WiFi Protected Setup
Your WiMAX Modem supports WiFi Protected Setup (WPS), which is an easy way to
set up a secure wireless network. WPS is an industry standard specification,
defined by the WiFi Alliance.
WPS allows you to quickly set up a wireless network with strong security, without
having to configure security settings manually. Each WPS connection works
between two devices. Both devices must support WPS (check each device’s
documentation to make sure).
74
User’s Guide
Chapter 6 The WIFI Configuration Screen
Depending on the devices you have, you can either press a button (on the device
itself, or in its configuration utility) or enter a PIN (a unique Personal Identification
Number that allows one device to authenticate the other) in each of the two
devices. When WPS is activated on a device, it has two minutes to find another
device that also has WPS activated. Then, the two devices connect and set up a
secure network by themselves.
6.4.5.1 Push Button Configuration
WPS Push Button Configuration (PBC) is initiated by pressing a button on each
WPS-enabled device, and allowing them to connect automatically. You do not need
to enter any information.
Not every WPS-enabled device has a physical WPS button. Some may have a WPS
PBC button in their configuration utilities instead of or in addition to the physical
button.
Take the following steps to set up WPS using the button.
Ensure that the two devices you want to set up are within wireless range of one
another.
Look for a WPS button on each device. If the device does not have one, log into its
configuration utility and locate the button (see the device’s User’s Guide for how to
do this). The WiMAX Modem’s WPS button is in the rear panel as shown next.
Figure 26 The WPS Button on the WiMAX Modem
Press the button on one of the devices (it doesn’t matter which). For the WiMAX
Modem you must press the WPS button for more than three seconds.
Within two minutes, press the button on the other device. The registrar sends the
network name (SSID) and security key through an secure connection to the
enrollee.
If you need to make sure that WPS worked, check the list of associated wireless
clients in the AP’s configuration utility. If you see the wireless client in the list,
WPS was successful.

The WAN Configuration Screens
7.1 Overview
Use the ADVANCED > WAN Configuration screens to set up your WiMAX
Modem’s Wide Area Network (WAN) or Internet features.
A Wide Area Network (or WAN) links geographically dispersed locations to other
networks or the Internet. A WAN configuration can include switched and
permanent telephone circuits, terrestrial radio systems and satellite systems.
7.1.1 What You Can Do in This Chapter
• The Internet Connection screen (Section 7.2 on page 79) lets you set up your
WiMAX Modem’s Internet settings.
• The WiMAX Configuration screen (Section 7.3 on page 82) lets set up the
frequencies used by your WiMAX Modem.
7.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
WiMAX
WiMAX (Worldwide Interoperability for Microwave Access) is the IEEE 802.16
wireless networking standard, which provides high-bandwidth, wide-range
wireless service across wireless Metropolitan Area Networks (MANs). ZyXEL is a
member of the WiMAX Forum, the industry group dedicated to promoting and
certifying interoperability of wireless broadband products.
In a wireless MAN, a wireless-equipped computer is known either as a mobile
station (MS) or a subscriber station (SS). Mobile stations use the IEEE 802.16e
standard and are able to maintain connectivity while switching their connection
from one base station to another base station (handover) while subscriber stations
use other standards that do not have this capability (IEEE 802.16-2004, for
User’s Guide
77
Chapter 7 The WAN Configuration Screens
example). The following figure shows an MS-equipped notebook computer MS1
moving from base station BS1’s coverage area and connecting to BS2.
Figure 27 WiMax: Mobile Station
WiMAX technology uses radio signals (around 2 to 10 GHz) to connect subscriber
stations and mobile stations to local base stations. Numerous subscriber stations
and mobile stations connect to the network through a single base station (BS), as
in the following figure.
Figure 28 WiMAX: Multiple Mobile Stations
A base station's coverage area can extend over many hundreds of meters, even
under poor conditions. A base station provides network access to subscriber
stations and mobile stations, and communicates with other base stations.
The radio frequency and bandwidth of the link between the WiMAX Modem and the
base station are controlled by the base station. The WiMAX Modem follows the
base station’s configuration.
Authentication
When authenticating a user, the base station uses a third-party RADIUS or
Diameter server known as an AAA (Authentication, Authorization and Accounting)
server to authenticate the mobile or subscriber stations.
78

Chapter 7 The WAN Configuration Screens
The following figure shows a base station using an AAA server to authenticate
mobile station MS, allowing it to access the Internet.

sessions. If you do not limit the number of NAT sessions a single
client can establish, this can result in all of the available NAT
sessions being used. In this case, no additional NAT sessions can
be established, and users may not be able to access the Internet.
Each NAT session establishes a corresponding firewall session. Use
this field to limit the number of NAT/firewall sessions each client
computer can establish through the WiMAX Modem.
If your network has a small number of clients using peer to peer
applications, you can raise this number to ensure that their
performance is not degraded by the number of NAT sessions they
can establish. If your network has a large number of users using
peer to peer applications, you can lower this number to ensure no

8.3 Port Forwarding
A NAT server set is a list of inside (behind NAT on the LAN) servers, for example,
web or FTP, that you can make accessible to the outside world even though NAT
makes your whole inside network appear as a single machine to the outside world.
Use the ADVANCED ( 進階 ) > NAT Configuration (NAT 設定 ) > Port
Forwarding screen to forward incoming service requests to the server(s) on your
local network. You may enter a single port number or a range of port numbers to
be forwarded, and the local IP address of the desired server. The port number
identifies a service; for example, web service is on port 80 and FTP on port 21. In
some cases, such as for unknown services or where one server can support more
than one service (for example both FTP and web service), it might be better to
specify a range of port numbers.
In addition to the servers for specified services, NAT supports a default server. A
service request that does not have a server explicitly designated for it is forwarded
to the default server. If the default is not defined, the service request is simply
discarded.
For example, let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP
server (A in the example), port 80 to another (B in the example) and assign a
default server IP address of 192.168.1.35 to a third (C in the example). You
assign the LAN IP addresses and the ISP assigns the WAN IP address. The NAT
network appears as a single host on the Internet.

8.4 Trigger Port
Some services use a dedicated range of ports on the client side and a dedicated
range of ports on the server side. With regular port forwarding you set a
forwarding port in NAT to forward a service (coming in from the server on the
WAN) to the IP address of a computer on the client side (LAN). The problem is
that port forwarding only forwards a service to a single LAN IP address. In order to
use the same service on a different LAN computer, you have to manually replace
the LAN computer's IP address in the forwarding port with another LAN
computer's IP address,
Trigger port forwarding solves this problem by allowing computers on the LAN to
dynamically take turns using the service. The WiMAX Modem records the IP
address of a LAN computer that sends traffic to the WAN to request a service with
a specific port number and protocol (a "trigger" port). When the WiMAX Modem's
WAN port receives a response with a specific port number and protocol
("incoming" port), the WiMAX Modem forwards the traffic to the LAN IP address of
the computer that sent the request. After that computer’s connection for that
service closes, another computer on the LAN can use the service in the same
manner. This way you do not need to configure a new IP address each time you
want a different LAN computer to use the application.

8.4.1 Trigger Port Forwarding Example
The following is an example of trigger port forwarding. In this example, J is Jane’s
computer and S is the Real Audio server.
Figure 39 Trigger Port Forwarding Example
96
Jane requests a file from the Real Audio server (port 7070).
Port 7070 is a “trigger” port and causes the WiMAX Modem to record Jane’s
computer IP address. The WiMAX Modem associates Jane's computer IP address
with the "incoming" port range of 6970-7170.
The Real Audio server responds using a port number ranging between 6970-7170.
The WiMAX Modem forwards the traffic to Jane’s computer IP address.
User’s Guide
Chapter 8 The NAT Configuration Screens
Only Jane can connect to the Real Audio server until the connection is closed or
times out. The WiMAX Modem times out in three minutes with UDP (User
Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet
Protocol).
Two points to remember about trigger ports:
Trigger events only happen on data that is coming from inside the WiMAX Modem
and going to the outside.
If an application needs a continuous data stream, that port (range) will be tied up
so that another computer on the LAN can’t trigger it.

Chapter 9 The System Configuration Screens
Domain Name
The Domain Name entry is what is propagated to the DHCP clients on the LAN. If
you leave this blank, the domain name obtained by DHCP from the ISP is used.
While you must enter the host name (System Name) on each individual computer,
the domain name can be assigned from the WiMAX Modem via DHCP.
DNS Server Address Assignment
Use DNS (Domain Name System) to map a domain name to its corresponding IP
address and vice versa, for instance, the IP address of www.zyxel.com is
204.217.0.2. The DNS server is extremely important because without it, you must
know the IP address of a computer before you can access it.
The WiMAX Modem can get the DNS server addresses in the following ways:
The ISP tells you the DNS server addresses, usually in the form of an information
sheet, when you sign up. If your ISP gives you DNS server addresses, enter them
in the DNS Server fields in the SYSTEM General screen.
If the ISP did not give you DNS server information, leave the DNS Server fields in
the SYSTEM General screen set to 0.0.0.0 for the ISP to dynamically assign the
DNS server IP addresses.
9.2 Dynamic DNS
Dynamic DNS allows you to update your current dynamic IP address with one or
many dynamic DNS services so that anyone can contact you (in NetMeeting, CUSeeMe, etc.). You can also access your FTP server or Web site on your own
computer using a domain name (for instance myhost.dhs.org, where myhost is a
name of your choice) that will never change instead of using an IP address that
changes each time you reconnect. Your friends or relatives will always be able to
call you even if they don't know your IP address.
First of all, you need to have registered a dynamic DNS account with
www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP
server that would still like to have a domain name. The Dynamic DNS service
provider will give you a password or key.
Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be
aliased to the same IP address as yourhost.dyndns.org. This feature is useful if
you want to be able to use, for example, www.yourhost.dyndns.org and still reach
your hostname.

The Service Configuration
Screens
10.1 Overview
The VOICE > Service Configuration screens allow you to set up your voice
accounts and configure your QoS settings.
VoIP (Voice over IP) is the sending of voice signals over the Internet Protocol. This
allows you to make phone calls and send faxes over the Internet at a fraction of
the cost of using the traditional circuit-switched telephone network. You can also
use servers to run telephone service applications like PBX services and voice mail.
Internet Telephony Service Provider (ITSP) companies provide VoIP service. A
company could alternatively set up an IP-PBX and provide it’s own VoIP service.
Circuit-switched telephone networks require 64 kilobits per second (kbps) in each
direction to handle a telephone call. VoIP can use advanced voice coding
techniques with compression to reduce the required bandwidth.
10.1.1 What You Can Do in This Chapter
• The SIP Setting screen (Section 10.2 on page 111) lets you setup and
maintain your SIP account(s) in the WiMAX Modem.
• The Advanced SIP Settings screen (Section 10.2.1 on page 112) lets you set
up and maintain advanced settings for each SIP account
• The QoS screen (Section 10.3 on page 119) lets you set up and maintain ToS
and VLAN settings for the WiMAX Modem.
10.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
SIP
The Session Initiation Protocol (SIP) is an application-layer control (signaling)
protocol that handles the setting up, altering and tearing down of voice and
User’s Guide
109
Chapter 10 The Service Configuration Screens
multimedia sessions over the Internet. SIP signaling is separate from the media
for which it handles sessions. The media that is exchanged during the session can
use a different path from that of the signaling. SIP handles telephone calls and can
interface with traditional circuit-switched telephone networks.
SIP Identities
A SIP account uses an identity (sometimes referred to as a SIP address). A
complete SIP identity is called a SIP URI (Uniform Resource Identifier). A SIP
account's URI identifies the SIP account in a way similar to the way an e-mail
address identifies an e-mail account. The format of a SIP identity is SIPNumber@SIP-Service-Domain.
SIP Number
The SIP number is the part of the SIP URI that comes before the “@” symbol. A
SIP number can use letters like in an e-mail address (johndoe@your-ITSP.com for
example) or numbers like a telephone number (1122334455@VoIP-provider.com
for example).
SIP Service Domain
The SIP service domain of the VoIP service provider (the company that lets you
make phone calls over the Internet) is the domain name in a SIP URI. For
example, if the SIP address is 1122334455@VoIP-provider.com, then “VoIPprovider.com” is the SIP service domain.
SIP Register Server
A SIP register server maintains a database of SIP identity-to-IP address (or
domain name) mapping. The register server checks your user name and password
when you register.
RTP
When you make a VoIP call using SIP, the RTP (Real time Transport Protocol) is
used to handle voice data transfer. See RFC 1889 for details on RTP.
Use NAT
If you know the NAT router’s public IP address and SIP port number, you can use
the Use NAT feature to manually configure the WiMAX Modem to use a them in the
SIP messages. This eliminates the need for STUN or a SIP ALG. You must also
configure the NAT router to forward traffic with this port number to the WiMAX
Modem.

Chapter 10 The Service Configuration Screens
10.1.3 Before you Begin
• Ensure that you have all of your voice account information on hand. If not,
contact your voice account service provider to find out which settings in this
chapter you should configure in order to use your telephone with the WiMAX
Modem.
• Connect your WiMAX Modem to the Internet, as described in the Quick Start
Guide. If you have not already done so, then you will not be able to test your
VoIP settings.
10.2 SIP Settings
Click VOICE > Service Configuration > SIP Setting to setup and maintain

10.2.1 Advanced SIP Settings
This section describes the features of the Advanced SIP settings screen.
10.2.1.1 STUN
STUN (Simple Traversal of User Datagram Protocol (UDP) through Network
Address Translators) allows the WiMAX Modem to find the presence and types of
NAT routers and/or firewalls between it and the public Internet. STUN also allows
the WiMAX Modem to find the public IP address that NAT assigned, so the WiMAX
112
User’s Guide
Chapter 10 The Service Configuration Screens
Modem can embed it in the SIP data stream. STUN does not work with symmetric
NAT routers or firewalls. See RFC 3489 for details on STUN.
The following figure shows how STUN works.
The WiMAX Modem (A) sends SIP packets to the STUN server (B).
The STUN server (B) finds the public IP address and port number that the NAT
router used on the WiMAX Modem’s SIP packets and sends them to the WiMAX
Modem.
The WiMAX Modem uses the public IP address and port number in the SIP packets
that it sends to the SIP server (C).
Figure 45 STUN
NAT
10.2.1.2 Outbound Proxy
Your VoIP service provider may host a SIP outbound proxy server to handle all of
the WiMAX Modem’s VoIP traffic. This allows the WiMAX Modem to work with any
type of NAT router and eliminates the need for STUN or a SIP ALG. Turn off a SIP
ALG on a NAT router in front of the WiMAX Modem to keep it from re-translating
the IP address (since this is already handled by the outbound proxy server).
10.2.1.3 Voice Coding
A codec (coder/decoder) codes analog voice signals into digital signals and
decodes the digital signals back into voice signals. The WiMAX Modem supports
the following codecs.
• G.711 is a Pulse Code Modulation (PCM) waveform codec. PCM measures
analog signal amplitudes at regular time intervals (sampling) and converts them
into digital bits (quantization). Quantization “reads” the analog signal and then
“writes” it to the nearest digital value. For this reason, a digital sample is usually
slightly different from its analog original (this difference is known as
“quantization noise”). G.711 provides excellent sound quality but requires
64kbps of bandwidth.
User’s Guide
113
Chapter 10 The Service Configuration Screens
• G.723 is an Adaptive Differential Pulse Code Modulation (ADPCM) waveform
codec. Differential (or Delta) PCM is similar to PCM, but encodes the audio signal
based on the difference between one sample and a prediction based on previous
samples, rather than encoding the sample’s actual quantized value. Many
thousands of samples are taken each second, and the differences between
consecutive samples are usually quite small, so this saves space and reduces
the bandwidth necessary.
However, DPCM produces a high quality signal (high signal-to-noise ratio or
SNR) for high difference signals (where the actual signal is very different from
what was predicted) but a poor quality signal (low SNR) for low difference
signals (where the actual signal is very similar to what was predicted). This is
because the level of quantization noise is the same at all signal levels. Adaptive
DPCM solves this problem by adapting the difference signal’s level of
quantization according to the audio signal’s strength. A low difference signal is
given a higher quantization level, increasing its signal-to-noise ratio. This
provides a similar sound quality at all signal levels. G.723 provides high quality
sound and requires 20 or 40 kbps.
• G.729 is an Analysis-by-Synthesis (AbS) hybrid waveform codec. It uses a filter
based on information about how the human vocal tract produces sounds. The
codec analyzes the incoming voice signal and attempts to synthesize it using its
list of voice elements. It tests the synthesized signal against the original and, if
it is acceptable, transmits details of the voice elements it used to make the
synthesis. Because the codec at the receiving end has the same list, it can
exactly recreate the synthesized audio signal.G.729 provides good sound quality
and reduces the required bandwidth to 8kbps.
10.2.1.4 MWI (Message Waiting Indication)
Enable Message Waiting Indication (MWI) enables your phone to give you a
message–waiting (beeping) dial tone when you have one or more voice messages.
Your VoIP service provider must have a messaging system that sends messagewaiting-status SIP packets as defined in RFC 3842.

10.3 QoS
Network traffic can be classified by setting the ToS (Type Of Service) values at the
data source (for example, at the WiMAX Modem) so a server can decide the best
method of delivery, that is the least cost, fastest route and so on.
Virtual Local Area Network (VLAN) allows a physical network to be partitioned into
multiple logical networks. Only stations within the same group can communicate
with each other.
User’s Guide
119
Chapter 10 The Service Configuration Screens
Your WiMAX Modem can add IEEE 802.1Q VLAN ID tags to voice frames that it
sends to the network. This allows the WiMAX Modem to communicate with a SIP
server that is a member of the same VLAN group. Some ISPs use the VLAN tag to
identify voice traffic and give it priority over other traffic.
Click VOICE > Service Configuration > QoS to set up and maintain ToS and
VLAN settings for the WiMAX Modem. QoS (Quality of Service) refers to both a
network's ability to deliver data with minimum delay and the networking methods
used to provide bandwidth for real-time multimedia applications.

1. INVITE
2. Ringing
3. OK
4. ACK
5.Dialogue (voice

6. BYE
7. OK
A sends a SIP INVITE request to B. This message is an invitation for B to
participate in a SIP telephone call.
B sends a response indicating that the telephone is ringing.
B sends an OK response after the call is answered.
A then sends an ACK message to acknowledge that B has answered the call.
Now A and B exchange voice media (talk).
After talking, A hangs up and sends a BYE request.
B replies with an OK response confirming receipt of the BYE request and the call is
terminated.
User’s Guide
121
Chapter 10 The Service Configuration Screens
10.4.2 SIP Client Server
SIP is a client-server protocol. A SIP client is an application program or device that
sends SIP requests. A SIP server responds to the SIP requests.
When you use SIP to make a VoIP call, it originates at a client and terminates at a
server. A SIP client could be a computer or a SIP phone. One device can act as
both a SIP client and a SIP server.
10.4.3 SIP User Agent
A SIP user agent can make and receive VoIP telephone calls. This means that SIP
can be used for peer-to-peer communications even though it is a client-server
protocol. In the following figure, either A or B can act as a SIP user agent client to
initiate a call. A and B can also both act as a SIP user agent to receive the call.
Figure 48 SIP User Agent
10.4.4 SIP Proxy Server
A SIP proxy server receives requests from clients and forwards them to another
server.
In the following example, you want to use client device A to call someone who is
using client device C.
122
The client device (A in the figure) sends a call invitation to the SIP proxy server
(B).
User’s Guide
Chapter 10 The Service Configuration Screens
The SIP proxy server forwards the call invitation to C.
Figure 49 SIP Proxy Server
10.4.5 SIP Redirect Server
A SIP redirect server accepts SIP requests, translates the destination address to
an IP address and sends the translated IP address back to the device that sent the
request. Then the client device that originally sent the request can send requests
to the IP address that it received back from the redirect server. Redirect servers
do not initiate SIP requests.
In the following example, you want to use client device A to call someone who is
using client device C.
Client device A sends a call invitation for C to the SIP redirect server (B).
The SIP redirect server sends the invitation back to A with C’s IP address (or
domain name).
User’s Guide
123
Chapter 10 The Service Configuration Screens
Client device A then sends the call invitation to client device C.
Figure 50 SIP Redirect Server
10.4.6 NAT and SIP
The WiMAX Modem must register its public IP address with a SIP register server. If
there is a NAT router between the WiMAX Modem and the SIP register server, the
WiMAX Modem probably has a private IP address. The WiMAX Modem lists its IP
address in the SIP message that it sends to the SIP register server. NAT does not
translate this IP address in the SIP message. The SIP register server gets the
WiMAX Modem’s IP address from inside the SIP message and maps it to your SIP
identity. If the WiMAX Modem has a private IP address listed in the SIP message,
the SIP server cannot map it to your SIP identity. See Chapter 8 The NAT
Configuration Screens for more information.
Use a SIP ALG (Application Layer Gateway), Use NAT, STUN, or outbound proxy to
allow the WiMAX Modem to list its public IP address in the SIP messages.
10.4.7 DiffServ
DiffServ is a class of service (CoS) model that marks packets so that they receive
specific per-hop treatment at DiffServ-compliant network devices along the route
based on the application types and traffic flow. Packets are marked with DiffServ
Code Points (DSCPs) indicating the level of service desired. This allows the
intermediary DiffServ-compliant network devices to handle the packets differently
depending on the code points without the need to negotiate paths or remember
state information for every flow. In addition, applications do not have to request a
particular service or give advanced notice of where the traffic is going.
124
User’s Guide
Chapter 10 The Service Configuration Screens
10.4.8 DSCP and Per-Hop Behavior
DiffServ defines a new DS (Differentiated Services) field to replace the Type of
Service (TOS) field in the IP header. The DS field contains a 2-bit unused field and
a 6-bit DSCP field which can define up to 64 service levels. The following figure
illustrates the DS field.
Figure 51 DiffServ: Differentiated Service Field
DSCP
Unused
(6-bit)
(2-bit)
DSCP is backward compatible with the three precedence bits in the ToS octet so
that non-DiffServ compliant, ToS-enabled network device will not conflict with the
DSCP mapping.
The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior),
that each packet gets across the DiffServ network. Based on the marking rule,
different kinds of traffic can be marked for different priorities of forwarding.
Resources can then be allocated according to the DSCP values and the configured
policies.

11.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
Voice Activity Detection/Silence Suppression/Comfort Noise
Voice Activity Detection (VAD) detects whether or not speech is present. This lets
the WiMAX Modem reduce the bandwidth that a call uses by not transmitting
“silent packets” when you are not speaking.
When using VAD, the WiMAX Modem generates comfort noise when the other
party is not speaking. The comfort noise lets you know that the line is still
connected as total silence could easily be mistaken for a lost connection.
Echo Cancellation
G.168 is an ITU-T standard for eliminating the echo caused by the sound of your
voice reverberating in the telephone receiver while you talk.

key (button) that generates the signal electronically. If the flash key is not
available, you can tap (press and immediately release) the hook by hand to
achieve the same effect. However, using the flash key is preferred since the timing
is much more precise. The WiMAX Modem may interpret manual tapping as
hanging up if the duration is too long

Speed Dial and Peer-to-Peer Calling
Speed dial provides shortcuts for dialing frequently used (VoIP) phone numbers. It
is also required if you want to make peer-to-peer calls.
In peer-to-peer calls, you call another VoIP device directly without going through a
SIP server. In the WiMAX Modem, you must set up a speed dial entry in the phone
book in order to do this. Select Non-Proxy (Use IP or URL) in the Type column
and enter the callee’s IP address or domain name. The WiMAX Modem sends SIP
INVITE requests to the peer VoIP device when you use the speed dial entry.
You do not need to configure a SIP account in order to make a peer-to-peer VoIP
call.

The Certificates Screens
13.1 Overview
Use the TOOLS ( 工具 ) > Certificates ( 憑證 ) screens to import public key
certificates on the WiMAX Modem.
The WiMAX Modem can use public key certificates (also sometimes called “digital
IDs”) to authenticate users. Certificates are based on public-private key pairs. A
certificate contains the certificate owner’s identity and public key. Certificates
provide a way to exchange public keys for use in authentication.
Public key certificates are used by web browsers to ensure that a secure web site
is legitimate. When a certificate authority such as VeriSign, Comodo, or Network
Solutions (to name a few) receives a certificate request from a website operator,
they confirm that the web domain and contact information in the request match
those on public record with a domain name registrar. If they match, then the
certificate is issued to the website operator, who then places it on his site to be
issued to all visiting web browsers to let them know that the site is legitimate.
13.1.1 What You Can Do in This Chapter
• The My Certificates screen (Section 13.2 on page 146) lets you import the
WiMAX Modem’s CA-signed certificates.
• The Trusted CAs screen (Section 13.3 on page 146) lets you import trusted
CA-signed certificates.
13.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
Certificate Authorities
A Certification Authority (CA) issues certificates and guarantees the identity of

The Remote Management
Screens
14.1 Overview
Use the TOOLS ( 工具 ) > Remote MGMT screens to control which computers can
use which services to access the WiMAX Modem on each interface.
Remote management allows you to determine which services/protocols can access
which WiMAX Modem interface (if any) from which computers.
You may manage your WiMAX Modem from a remote location via:
Table 55 Remote Management
•
Internet (WAN only)
•
ALL (LAN and WAN)
•
LAN only
•
Neither (Disable).
To disable remote management of a service, select Disable in the corresponding
Server Access field.
You may only have one remote management session running at a time. The
WiMAX Modem automatically disconnects a remote management session of lower
priority when another remote management session of higher priority starts. The
priorities for the different types of remote management sessions are as follows.

14.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
Remote Management Limitations
Remote management over LAN or WAN will not work when:
A filter in SMT menu 3.1 (LAN) or in menu 11.5 (WAN) is applied to block a Telnet,
FTP or Web service.
You have disabled that service in one of the remote management screens.
The IP address in the Secured Client IP field does not match the client IP
address. If it does not match, the WiMAX Modem will disconnect the session
immediately.
There is already another remote management session with an equal or higher
priority running. You may only have one remote management session running at
one time.
Remote Management and NAT
When NAT is enabled:
• Use the WiMAX Modem’s WAN IP address when configuring from the WAN.
• Use the WiMAX Modem’s LAN IP address when configuring from the LAN.
System Timeout
There is a default system management idle timeout of five minutes (three
hundred seconds). The WiMAX Modem automatically logs you out if the
management session remains idle for longer than this timeout period. The
management session does not time out when a statistics screen is polling.
SNMP
Simple Network Management Protocol (SNMP) is a protocol used for exchanging
management information between network devices. SNMP is a member of the
150
User’s Guide
Chapter 14 The Remote Management Screens
TCP/IP protocol suite. Your WiMAX Modem supports SNMP agent functionality,
which allows a manager station to manage and monitor the WiMAX Modem
through the network. The WiMAX Modem supports SNMP version one (SNMPv1)
and version two (SNMPv2). The next figure illustrates an SNMP management
operation.
Note: SNMP is only available if TCP/IP is configured.

Chapter 14 The Remote Management Screens
14.5 SNMP
An SNMP managed network consists of two main types of component: agents and
a manager.
Figure 64 SNMP Management Model
An agent is a management software module that resides in a managed device (the
WiMAX Modem). An agent translates the local management information from the
managed device into a form compatible with SNMP. The manager is the console
through which network administrators perform network management functions. It
executes applications that control and monitor managed devices.
The managed devices contain object variables/managed objects that define each
piece of information to be collected about a device. Examples of variables include
such as number of packets received, node port status etc. A Management
Information Base (MIB) is a collection of managed objects. SNMP allows a
manager and agents to communicate for the purpose of accessing these objects.
The WiMAX Modem supports MIB II that is defined in RFC-1213 and RFC-1215.
The focus of the MIBs is to let administrators collect statistical data and monitor
status and performance.
SNMP itself is a simple request/response protocol based on the manager/agent
model. The manager issues a request and the agent returns responses using the
following protocol operations:
• Get - Allows the manager to retrieve an object variable from the agent.
154
User’s Guide
Chapter 14 The Remote Management Screens
• GetNext - Allows the manager to retrieve the next object variable from a table
or list within an agent. In SNMPv1, when a manager wants to retrieve all
elements of a table from an agent, it initiates a Get operation, followed by a
series of GetNext operations.
• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.
14.5.1 SNMP Traps
The WiMAX Modem sends traps to the SNMP manager when any of the following
events occurs:
Table 59 SNMP Traps
User’s Guide
TRAP #
TRAP NAME
DESCRIPTION
coldStart (defined in RFC1215)
A trap is sent after booting (power on).
warmStart (defined in RFC1215)
A trap is sent after booting (software reboot).
authenticationFailure (defined
in RFC-1215)
A trap is sent to the manager when receiving
any SNMP get or set requirements with the
wrong community (password).
whyReboot (defined in ZYXEL- A trap is sent with the reason of restart before
MIB)
rebooting when the system is going to restart
(warm start).
6a
For intentional reboot:
A trap is sent with the message "System reboot
by user!" if reboot is done intentionally, (for
example, download new files, CI command "sys
reboot", etc.).
6b
For fatal error:
A trap is sent with the message of the fatal
code if the system reboots because of fatal
errors.

Check the hardware connections, and make sure the LEDs are behaving as
expected. See the Quick Start Guide and Section 1.2.1 on page 21.
Disconnect and re-connect the power adapter to the WiMAX Modem.
If the problem continues, contact your ISP.
The Internet connection is slow or intermittent.
The quality of the WiMAX Modem’s wireless connection to the base station may be
poor. Poor signal reception may be improved by moving the WiMAX Modem away
from thick walls and other obstructions, or to a higher floor in your building.
There may be radio interference caused by nearby electrical devices such as
microwave ovens and radio transmitters. Move the WiMAX Modem away or switch
the other devices off. Weather conditions may also affect signal quality.
As well as having an external antenna connector, the MAX-210HW2 is equipped
with an internal directional antenna. If you know the location of the base station,
orient the front of the WiMAX Modem (the side with the LEDs) towards the base
station. If you do not know the location of the base station, experiment by moving
the WiMAX Modem while observing the Strength Indicator LEDs for an increase
in received signal strength. The MAX-200HW2 and MAX-230HW2 do not have
internal antennas.
There might be a lot of traffic on the network. Look at the LEDs, and check Section
1.2.1 on page 21. If the WiMAX Modem is sending or receiving a lot of
information, try closing some programs that use the Internet, especially peer-topeer applications.
Disconnect and re-connect the power adapter to the WiMAX Modem.

17.4 Phone Calls and VoIP
The telephone port won’t work or the telephone lacks a dial tone.
Check the telephone connections and telephone wire.
Make sure you have the VOICE > Service Configuration > SIP Settings screen
properly configured (Chapter 10 on page 109).
I can access the Internet, but cannot make VoIP calls.
Make sure you have the VOICE > Service Configuration > SIP Settings screen
properly configured (Chapter 10 on page 109).
The VoIP LED should come on. Make sure that your telephone is connected to the
VoIP port (see the Quick Start Guide for information on connecting telephone
cables to the these ports).
You can also check the VoIP status in the Status ( 狀態 ) screen.
If the VoIP settings are correct, use speed dial to make peer-to-peer calls. If you
cannot make a call using speed dial, there may be something wrong with the SIP
server. Contact your VoIP service provider.
Problems With Multiple SIP Accounts
You can set up two SIP accounts on your WiMAX Modem. By default your WiMAX
Modem uses SIP account 1 for outgoing calls, and it uses SIP accounts 1 and 2 for
incoming calls. With this setting, you always use SIP account 1 for your outgoing
calls and you cannot distinguish which SIP account the calls are coming in
through. If you want to control the use of different dialing plans for accounting
purposes or other reasons, you need to configure your phone port in order to
control which SIP account you are using when placing or receiving calls.

DESCRIPTION
Web-based Configuration
and Management Tool
Also known as “the web configurator”, this is a firmwarebased management solution for the WiMAX Modem. You must
connect using a compatible web browser in order to use it.
High Speed Wireless
Internet Access
The WiMAX Modem is ideal for high-speed wireless Internet
browsing.
WiMAX (Worldwide Interoperability for Microwave Access) is a
wireless networking standard providing high-bandwidth,
wide-range secured wireless service. The WiMAX Modem is a
WiMAX mobile station (MS) compatible with the IEEE 802.16e
standard.
178
Firewall
The WiMAX Modem is a stateful inspection firewall with DoS
(Denial of Service) protection. By default, when the firewall is
activated, all incoming traffic from the WAN to the LAN is
blocked unless it is initiated from the LAN. The WiMAX
Modem’s firewall supports TCP/UDP inspection, DoS detection
and prevention, real time alerts, reports and logs.
Content Filtering
The WiMAX Modem can block access to web sites containing
specified keywords. You can define time periods and days
during which content filtering is enabled and include or
exclude a range of users on the LAN from content filtering.
Network Address
Translation (NAT)
Network Address Translation (NAT) allows the translation of
an Internet protocol address used within one network (for
example a private IP address used in a local network) to a
different IP address known within another network (for
example a public IP address used on the Internet).
Universal Plug and Play
(UPnP)
Your device and other UPnP enabled devices can use the
standard TCP/IP protocol to dynamically join a network,
obtain an IP address and convey their capabilities to each
other.
User’s Guide
Chapter 18 Product Specifications
Table 67 Firmware Specifications (continued)
FEATURE
DESCRIPTION
Dynamic DNS Support
With Dynamic DNS support, you can have a static hostname
alias for a dynamic IP address, allowing the host to be more
easily accessible from various locations on the Internet. You
must register for this service with a Dynamic DNS service
provider.
DHCP
DHCP (Dynamic Host Configuration Protocol) allows the
individual clients (computers) to obtain the TCP/IP
configuration at start-up from a centralized DHCP server. Your
device has built-in DHCP server capability enabled by default.
It can assign IP addresses, an IP default gateway and DNS
servers to DHCP clients. Your device can also act as a
surrogate DHCP server (DHCP Relay) where it relays IP
address assignment from the actual real DHCP server to the
clients.
IP Alias
IP alias allows you to partition a physical network into logical
networks over the same Ethernet interface. Your device
supports three logical LAN interfaces via its single physical
Ethernet interface with the your device itself as the gateway
for each LAN network.
Multiple SIP Accounts
You can configure multiple voice (SIP) accounts.
SIP ALG
Your device is a SIP Application Layer Gateway (ALG). It
allows VoIP calls to pass through NAT for devices behind it
(such as a SIP-based VoIP software application on a
computer).
Dynamic Jitter Buffer
The built-in adaptive buffer helps to smooth out the
variations in delay (jitter) for voice traffic (up to 60 ms). This
helps ensure good voice quality for your conversations.
Voice Activity Detection/
Silence Suppression
Voice Activity Detection (VAD) reduces the bandwidth that a
call uses by not transmitting when you are not speaking.
Comfort Noise Generation
Your device generates background noise to fill moments of
silence when the other device in a call stops transmitting
because the other party is not speaking (as total silence
could easily be mistaken for a lost connection).
Echo Cancellation
You device supports G.168 of at least 24 ms.
This an ITU-T standard for eliminating the echo caused by the
sound of your voice reverberating in the telephone receiver
while you talk.
Time and Date
Get the current time and date from an external server when
you turn on your WiMAX Modem. You can also set the time
manually.
Logging
Use the WiMAX Modem’s logging feature to view connection
history, surveillance logs, and error messages.
Codecs
Enhanced Variable Rate Codec (EVRC), G.711 (PCM µ-law
and a-law), G.729a, and G.723.1
Fax Support
T.38 FAX relay (FAX over UDP).
G.711 fax relay for fax calls and be able to renegotiate codec
to G.711 if a fax call is detected.

Call Park and
Pickup
Call park and pickup lets you put a call on hold (park) and then
continue the call (pickup). The caller must still pay while the call is
parked.
When you park the call, you enter a number of your choice (up to
eight digits), which you must enter again when you pick up the call. If
you do not enter the correct number, you cannot pickup the call. This
means that only someone who knows the number you have chosen
can pick up the call.
You can have more than one call on hold at the same time, but you
must give each call a different number.
User’s Guide
Call Return
With call return, you can place a call to the last number that called
you (either answered or missed). The last incoming call can be
through either SIP or PSTN.
Country Code
Phone standards and settings differ from one country to another, so
the settings on your WiMAX Modem must be configured to match
those of the country you are in. The country code feature allows you
to do this by selecting the country from a list rather than changing
each setting manually. Configure the country code feature when you
move the WiMAX Modem from one country to another.
Do not Disturb
(DnD)
This feature allows you to set your phone not to ring when someone
calls you. You can set each phone independently using its keypad, or
configure global settings for all phones using the command line
interpreter.
Auto Dial
You can set the WiMAX Modem to automatically dial a specified
number immediately whenever you lift a phone off the hook. Use the
Web Configurator to set the specified number. Use the command line
interpreter to have the WiMAX Modem wait a specified length of time
before dialing the number.
Phone config
The phone configuration table allows you to customize the phone
keypad combinations you use to access certain features on the
WiMAX Modem, such as call waiting, call return, call forward, etc. The
phone configuration table is configurable in command interpreter
mode.
